Grays Harbor Day Trip: Bowerman Birds & Westport Halibut

The South Coast of Washington doesn’t wait for you to plan ahead. In spring 2026, the window opened on two experiences you’d drive hours for — and both peaked in May. The Grays Harbor National Wildlife Refuge in Hoquiam was in the final days of one of the Pacific Coast’s most extraordinary wildlife events, while out at the Westport docks, the 2026 halibut season was running on designated days. Whether you’re a birder, an angler, or just someone who needs a genuinely good Sunday, the South Coast delivered — and both experiences return each spring.

The Last Days of Spring Migration at Bowerman Basin

Every spring, hundreds of thousands of shorebirds descend on the Grays Harbor Estuary during their northbound migration from South America and Central America toward breeding grounds in Alaska and the Arctic. The Grays Harbor National Wildlife Refuge — specifically the tidal flat ecosystem known as Bowerman Basin — sits at the center of this spectacle. The U.S. Fish & Wildlife Service describes Grays Harbor as one of the largest concentrations of shorebirds on the west coast, south of Alaska, and the numbers bear that out: in peak years, the flats host birds so numerous they seem to shift like a living tide.

The migration window runs from late April through mid-May, and May 10, 2026 sat squarely in it. The dominant species that week included Western sandpipers and dunlins — which together account for roughly 80 percent of the birds present — along with short-billed and long-billed dowitchers, black-bellied plovers, red knots, and semipalmated plovers. These birds are fueling up on the estuary’s rich mudflat invertebrates before pushing north. The urgency of their schedule means they’re concentrated, active, and visible in extraordinary numbers.

The Sandpiper Trail is your access point: a wooden boardwalk loop that leads through salt marsh and alder-cottonwood forest out to open benches overlooking the intertidal flats. The trail is open sunrise to sunset year-round, and there is no entrance fee. Reaching the trailhead requires a short 1/3-mile walk from the parking area at 1000 Airport Way, Hoquiam — through a cooperative agreement between the U.S. Fish & Wildlife Service and the Port of Grays Harbor, which manages the adjacent airfield.

The tide is everything here. Birding is best within three hours of high tide, when rising water pushes the shorebirds off the exposed flats and concentrates them near the boardwalk trail. Check the tide table at tides.net before you go, and aim to arrive about two hours before high water. There are no restrooms or potable water at the refuge, so come prepared. The payoff on a good tidal morning — a wall of sandpipers lifting and wheeling over the gray-green water — is one of those sights that recalibrates your sense of what the natural world can do. Reach the refuge at (360) 753-9467 through the Nisqually National Wildlife Refuge Complex.

Westport Halibut: The 2026 Season

Forty miles down the coast, Westport was operating in full halibut mode. The Washington Department of Fish and Wildlife opened Marine Area 2 — the Westport-Ocean Shores zone — to recreational halibut fishing on April 30, 2026, with designated open days running through May 31, and the season later continued on designated days through June 30. Sunday, May 10, 2026 was one of the May open days.

The 2026 schedule for Marine Area 2 ran Tuesdays, Thursdays, Fridays, and Sundays through the end of May, then Tuesdays, Thursdays, and Sundays from June 2 through June 30. The daily catch limit was one halibut, and the annual limit was six per angler. There was no minimum size restriction. All anglers were required to record their catch on a WDFW catch record card — also available as an electronic version through the WDFW’s MyWDFW and Fish Washington mobile apps.

Westport holds the coast’s largest charter boat fleet, and most of the action happens far offshore around the edges of Grays Canyon, with depths reaching 600 feet or more. Charter trips typically depart well before dawn and return by early afternoon — make sure to confirm departure times when you book. Several Westport operators booked halibut trips for the May and June open days, and availability on prime Sunday slots filled quickly. A solid starting point for the current charter fleet lineup is experiencewestport.com.

One practical note from the 2026 season: the fishery could close early if the quota for Marine Area 2 — set at 65,857 pounds for 2026 — was reached. In any season, always confirm that the area is open before heading to the dock by checking wdfw.wa.gov or the WDFW emergency fishing rules page. Quota tracking information is updated in-season.

Plan Your Visit

For Bowerman Basin: Drive to 1000 Airport Way, Hoquiam, WA 98550. Parking is free, the Sandpiper Trail is open sunrise to sunset, and there is no entrance fee. Time your visit to arrive within three hours of high tide for the best shorebird viewing. The migration window closes around mid-May each year — in 2026, the May 10 weekend was the time to go, and the birds return on the same late-April-to-mid-May schedule each spring. Contact the refuge through the Nisqually NWR Complex at (360) 753-9467, or visit fws.gov/refuge/grays-harbor.

For Westport halibut: In 2026, the open Sundays after May 10 were the 17th and 24th, with additional designated days through June 30; for the next season’s dates, visit experiencewestport.com for the charter fleet directory, or contact operators directly to check availability. Bring or download a WDFW catch record card before boarding. For in-season closures or quota updates, visit wdfw.wa.gov. The drive from Hoquiam to Westport is approximately 25 minutes via US-12 and State Route 105 — putting both stops on the same day trip if you time the tides right.
